CHARLES STASTKA, OF PITTSBURG, PENNSYLVNIA..

MAN GLE Specification of Letters Patent.

Patented Dec. e, i908.

Application led March 31, 1908. Serial N o. 424,388.

To all whom 'it may concern:

Be it known that I, CHARLES STASTKA, a subject of the Emperor ofAustria-Hungary, residing at Pittsburg, in the county of Allegheny andState 4of Pennsylvania, have invented certain new and usefulImprovements in Mangles, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to mangles, and to cert-ain new and usefulimprovements upon my mangle as disclosed in an application filed Feb.13th, 1908, Serial No. 415,639.

In the present application, I have devised novel vacuum cylinders to beused in lieu of the dash pots of my former invent-ion and a simplereversing device for controlling the movement of the pin rack of mymangle.

These improvements will be presently described in detail and referencewill now be had to the drawing forming a part of this specification,wherein,

Figure 1 is a longitudinal sectional view of my mangle, Fig. 2 is a planof the same, Fig. 3 is a front elevation of my reversing device, Fig. 4is a side elevation of the same, Fig. 5 is an end view of the mangle,and Fig. 6 is a horizontal sectional view of a portion of the mangletaken on the line .7aof Fig. 1. Fig. 7 is a detail view, showing theexhaust valve mechanism.

In the accompanying drawings, I have illustrated my mangle or laundrymachine as comprising a suitable bed 1 having side frames 2. Between theside frames is arranged a reciprocating device comprising a box-likestructure 3 adapted to bear directly upon the rolls 4 upon which thefabric or clothes are wound to be smoothed and treated by the mangle.The box-like structure 3 is filled with suitable material (not shown) toadd weight to the same, whereby when the device is reciprocatedsufficient pressurewill be exerted upon the rolls 4.

Upon each end of the box-like structure 3, I locate a guide 5 having anelevated inverted vacuum cylinder 6, said vacuum cylinders communicatingby a pipe 7 with a valve 8, the casing of the latter adapted tocommunicate with a vacuum pump (not shown), whereby said cylinders canbe eX- hausted of air. Arranged in each vacuum cylinder is a piston head9 having a depending piston rod 10 supporting a pin rack 11, the ends ofsaid rack being housed by the guides 5.

The side frames 2 intermediate their ends are provided with a transversebeam 12, providing bearings fora driven shaft 13. This shaft through themedium of gear wheels 14 drives a shaft 15, said shaft having a starwheel 16 adapted to mesh with pins 17 carried upon one side of the rack11. The opposite side of the rack 11 adjacent to its ends is providedwith pins 18 adapted to engage a reversing device 19 arranged upon thebeam 12. The reversing device 19 is cut away to provide twosemi-circular paths 20 for the pins 18, also with a roller bearing 21for the upper edge of the rack 11.

In operation, I will .assume that a rotary movement is imparted to theshaft 13, and that through the medium of the gear wheels 14 the shaft 15is driven. The star wheel 16 carried by said shaft will impart areciprocating movement to the pin rack 11, and as this pin rack isconnected to the boxlike structure 3, said structure will bereciprocated upon the bed 1. Assuming that one end of the pin rack 11 isreached, the pin 18 at that end of the rack will contact with thereversing device and will ride around upon the path 20 of the reversingdevice, also the pin rack, placing the pin 17 thereof in engagement withthe under side ofthe star wheel 16. The pin rack will then be moved inthe opposite direction until the other end of the pin rack is reached atwhich time the pin 18 at that end thereof contacts with the reversingdevice Vand starts the rack in the opposite direction. During thismovement of the pin rack, the same is maintained in a horizontalposition by the piston heads 9 within the vacuum cylinders 6, but thebox-like structure can be tilted whenever it is necessary to place a newroll of clothes under the reciprocating device.

The rollers 22 are provided for partially supporting the box likestructure3, during the movement of the latter. y

Having now described my invention what I claim as new,-is:

1. In a mangle, the combination with a y bed, and a plurality of rollsmounted upon said bed, of a box-like structure adapted to bereciprocated upon said rollers, vacuum cylinders carried by saidbox-like structure, a pin rack, piston heads connected to said pin rackand adapted to move in Asaid vacuum cylinders, a revoluble star wheelfor moving said pin rack, a reversing device supported above said bedrand having semicircular paths, pins carried by said Y,pin rack forengaging` the paths of said reversing device for reversing the movementofV said pin rack and said box-like structure.

2. In a mangle, the combination of a bed, a reciprocating deviceYarrangedY on .said bed, rolls interposedbetween said bed and saiddevice, a pin rack for reciprocatingsaid device7 vacuum cylinders forcushioning said vvpinrrack, and a reversing device arranged 10 .abovesaldbed for lmpartlng reverse movements Lto said pin rack.

In testimony whereof aiX my signature n the presence of two Witnesses.
